Title: Seal for gas turbine regenerative heat exchanger - comprises sealing strip with membrane clamped by leaf spring to contact rotary heat storage disc
Inventor: WIEGARD KLAUS
IPC: F28D19/04
Filed: 1978-10-28
Abstract: One leg of a leaf spring has a cross-section roughly in the form of a "V", with a flat outer section fixed under pretension to a clamping strip holding one leg of a "U"-section membrane for sealing the gas channels of a regenerative heat exchanger, in a gas turbine unit for propelling a vehicle. The seal consists of the membrane and a sealing strip in contact with a rotary heat storing body. The clamping strip holds the one leg of the membrane against the sealing strip, whilst the leaf spring holds the other leg of the membrane against the opposing wall of the housing. From the flat outer section welded to the clamping strip, the one leg of the leaf spring has an inwards and an outwards inclined short arch blending into an extended inwards inclined arch culminating in an outwards curved zone at the tip of the "V" which also is pretensioned against the clamping strip. From there the free leg of the leaf spring continues with an outward inclined curve which holds the other leg of the membrane.

Patent DE-2854710-A1 (DE)
Title: Air desiccator cartridge - has absorbent in concentric inner cylinder with heated central outflow tube
Inventor: KRAEMER WILHELM
IPC: B01D53/26
Filed: 1978-12-18
Abstract: A desiccator cartridge, for use e.g. in air blast circuit breakers, contains the active moisture absorbent in an inner cylinder within a cylindrical housing. The air enters and leaves the inner cylinder through perforated end plates and leaves the cartridge through a central tube in the opposite direction. This results in a better air flow, specially during the desorption. Channeling which is detrimental for optimum drying is eliminated and the beads do not move relative to each other. This prevents abrasion and dust formation.

Title: Controller for keyboard electronic musical instruments - uses shift register for transmission of key signals onto magnetic tape
Inventor: LIEB ERHARD DIPL ING
IPC: G10H1/00
Filed: 1979-02-08
Abstract: A switching control circuit for keyboard electronic musical instrument allows key signal to be stored on magnetic tape. The output of any of the keys is transmitted over OR gates to power driver stages to produce the notes. The key signals are also entered into a shift register and are clocked at a controlled rate into a transfer register. From the latter signals are amplified and stored in magnetic tape cassette form. Replay from a cassette is over a selector switch, amplifier and into an output register. A decoder register coupled to additional decoders, bistable and selector allows delays to be introduced to provide exact reproduction. Signals are entered into a register for transmission to the drive stages over the OR gates.

Title: Water supply control unit for hospital etc. - adds constant amount of disinfectant to water from mains supply
Inventor: WIENHOLD WILLY
IPC: E03C1/046
Filed: 1979-05-09
Abstract: The water supply control unit, e.g. for hospital allows mains drawn water to be supplied with a specific level of disinfectant added. The temp. controlled (5) mixing value draws water from the mains (3, 4) and passes it over a constant flow regulator (10). Flow takes place when a solenoid valve is actuated from the controller (27) and is passed to outlet (13). Disinfectant is drawn from a supply tank, over a line (16) with a fine flow regulator (15). This flow passes over a main flow regulator (21) and into the main flow. Pressure is monitored (12) and used to control the supply outlet.

Title: Monitoring profiles of ground combustion engine cylinder bolts - using laser projection and position dependent transducer intensity comparison
Inventor: HOCHHEIM DIETER
IPC: G01B11/24
Filed: 1979-07-06
Abstract: The arrangement for monitoring the longitudinal profiles of ground cylinder bolts for internal combustion engines to given dimensions is a rapidly and precisely operating arrangement both evaluating and indicating the profile. The bolt is placed in a prismatic holder and transversely illuminated by a laser beam producing a piecewise magnified projection of the bolt profile whilst the holder is moved in the bolt longitudinal direction. A position transducer determines the beam position w.r.t. the bolt holder and a photoelectrical transducer measures the beam intensity in the plane of projection. The transducer signal is compared with a reference signal for each position. A warning signal is produced for an excessive signal difference. The entire profile is displayed on a visual display connected to the processor.

Title: Energy saving transmission for car - has automatic freewheel when running downhill and for regenerative braking
Inventor: GRESSER GERMAN
IPC: B60K23/00
Filed: 1979-10-17
Abstract: The car transmission provides an automatic freewheel when the vehicle is on overun, or when running downhill. It eliminates transmission drag and can also switch off the engine until the throttle is re-applied. The system operates with a failsafe time delay to prevent the engine from cutting out every time the throttle panel is lifted e.g. when changing gear. A regenerative braking control can be included to store energy otherwise lost.
Patent DE-2943268-A1 (DE)
Title: Peeling shells of boiled eggs - by introducing eggs into cylinder through which water is passed, the cylinder performing circular motion about horizontal axis
Inventor: FUJII NORIOMI
IPC: A47J43/14
Filed: 1979-10-26
Abstract: Peeling of the shells of boiled eggs is realised continuously, promptly and simply by introducing the boiled eggs into a cylinder through which water is flowing, the cylinder performing circular movement about a substantially horizontal axis With the magnitude of the circular movement increasing gradually from an initial portion toward a terminal end portion. The boiled eggs are firstly made to collide with the inner surface of the cylinder by small circular movement of the cylinder, and rendered more elastic with the eggshells of fine fragments, to the degree that the shell membrane remains unbroken. Next, the shell membrane is broken by applying a whirling water stream and a centrifugal force generated by large circular motion. The boiled egg contents are then sepd. from the eggshells so smoothly as to be slipped out of their shells.
